A normal ERG result helps confirm Best’s because the disease disrupts retinal pigment epithelium (RPE) depolarization, not the rod and cone receptors evaluated during ERG.
What causes vitelliform?
Best vitelliform macular dystrophy (BVMD) is a genetic form of macular degeneration (damage to a part of the eye called the macula) that occurs in about 1 in 10,000 individuals. The physical cause of BVMD is breakdown of the tissue in the retina called retinal pigment epithelium (RPE).
Is vitelliform bilateral?

What age does adult Vitelliform dystrophy usually present at?

Is Retinoschisis hereditary?
Inheritance. Juvenile retinoschisis is inherited in an x-linked recessive pattern. The gene associated with this condition is located on the X chromosome , one of the two sex chromosomes .
